HARRISON TAYLOR CRONK, OF NEW YORK, N. Y.

FLOAT CONTROL.

To all whom, it may concern:

Be it known that I, HARRISON T. CRONK, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and Improved FloatControl, of which the following is a full, clear, and exact description.

My invention relates toa float control for a flush tank, and an objectof my invention is to provide a flush tank having but one valve, and inwhich there are no valves connected with the float, thereby eliminatingleakage incidental to float control valve mechanisms now in common use.

With the above and other objects in view, as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and more particularly pointedout in the appended claims.

Reference is to be had to the accompany ing drawings, forming a part ofthis specification in which similar characters of reference indicatecorresponding parts in all the figures, and in which Figure 1 is a sideelevation showing a preferred embodiment of my invention in position toflush a closet bowl; Fig. 2 is a vertical sectional view taken throughthe tank shown in Fig. 1 and on the line 2-2 of Fig. 3; and Fig. 3 is atransverse sectional view taken on the line 3-3 of Fig. 2 and looking inthe direction of the arrow.

In Fig. 1, I have shown a closet bowl A, positioned on one side of apartition B, which partition carries on its opposite side the tank Cmore particularly forming the subject-matter of my invention. The tank 0is connected to the bowl by means of an elbow D, within which elbow is aspring controlled valve E actuated by a handle F located adjacent thebowl A. Water is conveyed to the tank through a water pipe G.

For convenience in construction, the tank C is shown to be of twocylindrical parts 1 and 5 threaded together at 6. The opposite outerends of the cylindrical sections are formed into cone-shaped ends 7, theupper end terminating in a threaded nipple 8 in engagement with thewater pipe Gr and'the lower end formed int-o a nipple 9 in thread edengagement with the elbow D, the outlet Specification of Letters Patent.

of thenipple 9 being larger than the inlet of the nipple 8.

Floating within the tank C is a hollow ball float 10 of a diameterslightly less than the diameter of the cylindrical sections 4 and 5. Asthis float is lighter than the amount of water displaced by it, saidfloat is normally positioned at the top of the section 1, as shown infull lines in Fig. 2, so that opening the valve E by means of the handleF, will cause the water to rush from the tank C through the nipple 9into the bowl A. The rush of the water will carry the ball float 10 tothe bottom of the tank, to the position shown in dotted lines in Fig. 2,and will rest on the rubber ring gasket 11, closing communicationbetween the tank and its outlet, permitting the tank to be filled fromthe pipe G. A by-pass 12 of relatively small bore has one of its endsopening into the tank above the position of the float when at the bottomof the tank, and its opposite end opening into the tank below the floatwhen in said position. By means of this bypass water will be fed fromabove the float to the space below the float filling up this space,which will equalize the water pressure on the top and bottom of thefloat, permitting the latter to rise to its position at the top of thetank, to be again actuated to flush the bowl.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: 2

1. In a tank, a water inlet at the top thereof, a water outlet at thebottom thereof,

valve seats at the top and bot-tom of said tank, a single ball floatwithin said tank adapted when the tank is full, to rest against saidupper valve seat to close the inlet, said outlet being of relativelylarger bore than the inlet, and a valve controlling the passage of waterthrough said outlet, whereby the opening of said valve will cause saidtank to empty and position said ball float on said lower valve seat, toclose said outlet.

2. In combination, a closed tank continually open to a water supply andhaving an outlet at its lower end, a float adapted to close said outlet,a continually opened bypass connecting the tank immediately above saidfloat with the tank immediately below said float, whereby anuninterrupted stream may pass through the tank during the filling of thesame.

3. In a cylindrical tank having an inlet at its upper end and an outletat its lower end, a float valve of a diameter slightly less than thediameter of the tank normally closing said inlet when the tank is filledwith water and adapted when the tank is empty, to close said outlet aring gasket within said tank adjacent said outlet adapted to carry thefloat while the tank is being filled, and a by-pass connecting said tankabove said gasket with part of the tank below said gasket.

4. A tank having an outlet at the bottom and an inlet at the topthereof, a manuallyeontrolled valve normally closing. said outlet, avalve seat adjacent the bottom of said tank, a float closing said inletwhen the tank is filled and resting on said seat when the tank isfilling, closing fluid communication between the portion of the tankabove said seat and the portion below the seat, and a relatively smallby-pass connecting the portion above the seat with the portion below theseat, whereby the portion between the valve and the seat will be filled,whereby the float will be unseated to raise and close said inlet.

5. In a tank having an inlet at the upper end and an outlet at its lowerend, a float valve normally closing said inlet when the tank is filledand adapted when the tank is empty to close said outlet, and a valveseat adjacent said outlet adapted to carry said float while the tank isbeing filled, and a hypass straddling said seat and connecting the partof the tank above with the part of the Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents.Washington, I).
